CHAIR DESK.

Application filed February 11, 1920. Serial No. 357,7i38.k

To all whom t may concer/a.:

Be 1t known that I, CHARLES J. AKEssoN, a citizen of the United States,residing at- San Bieg'on in the county of San Diego and State ofCalifornia, have invented a certain new "and useful Chair Desk, of whichthe following is aV specification.

My invention relates to a desk adapted to be supported on the arms of achair for reading, writing and the like and the objects of my inventionare: first, to provide a desk which may be readily positioned on thearms of a chair in front of the user for reading, writing and the like;second, to provide a desk of this class which is applicable for use inconnection with the various makes of arm chairs; third, to provide adesk of this class which may be tilted to varying angles to suit;fourth, to provide a desk of this class which will facilitate thestudyingof two or more books in conjunction where they pertain ytosimilar" subject matter; fifth, to provide a desk of this class whichwill support books, large magazines, journals and the like thus addingto the comfort in reading them; sixth, to provide a desk of this classwhich is applicable foruse for writing, drawing and the like as well asa book support andy Seventh, to provide a desk of this class which issimple and economi-cal of construction` durable, easy to adjust intovarying positions relatively to the arms of the chair and making itapplicable for use with varying shaped arms of chairs.

lilith these and other objects in view as will appear hereinafter myinvention consists of certain novel features of construction,combination and arrangement of parts and portions as will be hereinafterdescribed in detail and particularly set forth in the appended claims,reference being had to the accompanying drawings and to the charactersof reference thereon which form a part of this application in which:

Figure 1 is a perspective view of my desk shown mounted in position on achair ready for use and showing tilting positions by dotted lines; F ig,2 is an enlarged detailed perspective view of the support for engagingthe arm of the chair and showing the desk support and arm fragmentarily;Fig. 3 is a bottom view ofthe desk showing the chair arm engagingmembers fragmentarily to facilitate the illustration and showing bydotted lines varying positions of the shift'- able supports; Fig. 4 isan end view thereof; Fig. 5 is a. sectional view through 5 5 of Fig. 3on an enlarged scale; Fig. 6 is a perspective view showing the meansofsupporting the arm engaging member in a slightly modified form fromthatof Figs. l to inclusive shown in connection with an upholsteredchair arm and Fig. 7 is a fragmentary sectional view on the line 7-7 ofFig. r6. f

Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawings.

The table member 1, shiftable supports 2, cleats 3, clamp bolts a, chairarm engaging members 5, clamp bolts 6, and adjustable lug 7 constitutethe principal parts and portions of my chair desk in its preferred form.

The table member l which is preferably a rectangularly shapedy member isslightly wider than the arms of the cha-ir but may be any suitableshape. or size and it is preferably provided along its lower edge with aledge 1a to prevent articles'placed thereon from slipping off and tohold a book or other article in position.

Secured on the bottom side of this table member l at its opposite endsare av pair of cleats 3 provided with elongated holes 3 therein and theyare spaced apart from the table l except at the ends where they aresecured. Mounted behind these cleats 3 are the ends of the shiftablesupports 2,

the ends of which are provided with holes adapted for the bolts 4 to fittherein and their other ends are provided with elongated holes Qa andadapted for the bolts 4. These bolts i are provided with nuts a thereon,preferably knurled to facilitate their being turned by hand thusproviding for shifting the supports 2 so that they may be spread furtherapart or closer together or may be shifted so that they are on varyingangles as shown by dotted lines in Fig. 8 to suit varying angled chairarms. These shiftable supports 2 are provided with eX- tended portionsat their middle provided with a hole adapted for the bolt 6 andpivotally mounted on this bolt 6 is the chair arm engaging member 5which is also provided with an extended portion t'L and these members 5kand 2 are held in certain relative positions to each other by frictionalcontact by means of the bolt 6 which is provided with a knurled nut 6athereon to facilitate Vits beingturned by hand. Ad-

arms.

it will be noted that the chair arm engaging surface of the member 5 isprovided with a felt or rubber surface topi-'event marring thechalir'Afinish and that the inner surface of the lug 7 is also provided withsuch` surface. Y j

In. the modified form of.V construction shownV in Figs. 6' and a'Vinstead of the lug 7 there is provided a bifurcated member S on whichis pivotally mounted a curved latch member 9 which is provided with atorsion sprino` 10 tending to hold it inwardly against the chair arm atall times. This latch isprovided with a knob 9 to be gripped by the handto facilitate the i'emovingA of the desk from. the chair.

Though have shown and described a particular construction, combinationand arrangement of parts and portions l do not wish to be limited tothis particular construction, combination and arrangement but desire' toinclude in the purview of my invention the construction, combination andarrangement substantially as set forth in the appended claims.

lt is yobvious that with this construction there is provided Va deskwhich may be used for reading, writing and so forth, which may bereadily `position-ed on the arms of a chair and readily removedtherefrom, which is adjustable torvarying angles for providing"V theproper tilt to the table portion.

That it is supported in such a manner that the supports may be shiftedlinwardly or outwardly for Varying width chair arms and may be shifted tovarying angles for application to varying angled chair arms,

l-lavlng thus Vdescribed my invention what l claim as new and desire tosecure by Letters Patent, is:

chairdesk, including supporting members resting' longitudinally a'longthe upper side of both of the chair arms, shiftable lugs mounted onsaidV supporting members, vertically adjustable therewith, formingvarying grooves between said supporting members and a portion lof thelugs, adapt-ed to i-ecei-v'ey the edges of the chair arms, othersupports pivotally mounted.V on and frictionally secu-red to saidsupports, andata-ble member shiftalbly mounted on ,said support.

2. A chair desk, including artable member, means for supporting. saidtable member oni a chair' arms, including a pair of spaced apartsupporting' members secured.

near each endof saidv table member, other supporting members'sl'iiftable sidewise and at varying angles to said first mentionedsupporting' members, and other supporting members pivotallyr mountedthereon and frictionall-y secured thereto, adapted to engage the chairarms' and be supported thereon. Y

3f, A chair desk, including a table niem-A ber', means for supportingsaiid table menib'er on af chair arms', including. a pair of spacedapart supporting members secured near each end of said table member,other supporting members shiftaible sidewise and at varying angles tosaid first mentioned supporting members, other supporting memberspivotally mounted thereon and frictionally se'curedthereto, adapted toengage the chair arms and be supported thereon, and lngmeansadjustab'ly` mounted on said last mentioned supports, formingVgrooves adapted tol receive the edges of the chair arms, whereby saidtable is supported on said chair arms and adapted to be adjusted side'-wise', forwardly and backwardly and on any angle relatively to the chairarms.

ln testimony whereof, I have hereunto set my hand at San Diego',California, thisth day of February, 1920.

CHARLES J. moisson.
